@Ondine14 A small protrusion would manifest in the area behind the door, being a small series of wispy tendrils made of what seemed like ordinary darkness. After a moment, these small little wisps would rip upwards, reaching a rapidly-increasing height and width until able to dwarf even most dragons, in size. These dark, monstrous protrusions would give off a sensation of immense fear. Being that they were new, it would only be a fear that would wash over anything within the area, however prolonged exposure would lead to paranoia of almost anything, and if exposed to it long enough, able to drive those infected legitimately insane.
Kuroshine was preparing.
